3. COM Express Pinouts and Signal Descriptions
The following information is a summary of the most important information regarding pinout and signal description in the official PICMG
COM.0 Rev 2.0 (soon 2.1)
The pinout is described here to emphazise issues that have not been followed in the past. The following description may still contain small
inacuaracies; in case of doubt, the offical design guide of PICMG should be consulted.
3.1. AB / CD Pin Definitions
All pins in the specification are described, including those not supported on the Express-IB. Those not supported on the Express-IBE2
module are crossed out
